Sometimes actors even talk about spirituality when touching the topic of acting. For example:
As an actor you are more like a medium. …. You just become a garment that something else puts on. A lot of people sit up there and do impersonations of other folks instead of allowing that spirit.
Another example:
[0:30] Cause it’s very spiritual what we do as actors. …. You are allowing this character to use your body as a vessel.
It can get even deeper:
Two voices came out of you …. You’re channeling.
